It will be analysed at the same time, not only the different ideologies that, related to that event, had an influence on the resolution of health-illnesses problems, but also the grade of commitment and the transactions that the people involved were capable of reaching. Finally, the dynamic of that incident will be interpreted in the context of certain ideological and political configurations in the Jujuy of that historical period. The bibliographic material investigated comes from local journalistic articles.
